这是一个关于 Hadoop 的警告信息，告诉您使用的脚本已过时，应改用 start-dfs.sh 和 start-yarn.sh 脚本来启动 Hadoop。此外，还提示无法加载本地 Hadoop 库，因此使用内置的 Java 类。最后，向您展示开始启动 Hadoop 的节点名称。

同样，这不是一个问题，而是一堆 npm 的警告信息。这些警告信息是告诉你使用的一些库已经被废弃了，建议你更新或者替换掉这些库。比如：

- `stable` 库已经被废弃，因为现代的 JavaScript 已经保证了 `Array#sort()` 是一个稳定的排序。
- `source-map-url` 库已经被废弃，建议使用其他替代库。
- `@hapi/bourne` 和 `@hapi/topo` 库已经被废弃，建议升级到新版本的 `@hapi` 库。
- `eslint-loader` 库已经被废弃，建议使用 `eslint-webpack-plugin`。
- `chokidar` 库已经被废弃，建议升级到新版本的 `chokidar` 库。
- `html-webpack-plugin` 库的 3.x 版本已经不再支持，建议升级到新版本的库。
- `uuid` 库的旧版本可能在某些情况下使用 `Math.random()`，存在问题，建议升级到新版本的库。

还有其他的警告信息也是类似的，建议你根据警告信息逐一解决这些问题。

2023-05-30T07:36:33.461969Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

这个错误信息表示您在使用 `--initialize` 初始化 MySQL 数据库时，MySQL 数据目录中已经存在了文件，因此 MySQL 无法继续初始化。可能是由于之前已经安装过 MySQL，或者是在数据目录中手动创建了一些文件导致的。

解决此问题的方法是：

1. 删除 MySQL 数据目录中的所有文件。您可以使用以下命令删除 MySQL 数据目录：

sudo rm -rf /var/lib/mysql/*

2. 重新执行 `--initialize` 命令以初始化 MySQL 数据库。例如，如果您要以默认设置初始化 MySQL 数据库，可以使用以下命令：

sudo mysqld --initialize

请注意，在执行 `--initialize` 命令之前，确保您已经备份了 MySQL 数据库中的所有数据，以防止数据丢失。
